Java Enum toString()

In Java, the toString() method is a member of the Object class, which is the superclass of all objects in Java. The toString() method returns a String representation of an object.

In the case of an enum type, the toString() method returns the name of the enum value as a String.

Here's an example of how to use the toString() method with an enum in Java:

public enum Size {
    SMALL("S"), MEDIUM("M"), LARGE("L"), EXTRA_LARGE("XL");

    private String abbreviation;

    private Size(String abbreviation) {
        this.abbreviation = abbreviation;
    }

    public String getAbbreviation() {
        return abbreviation;
    }

    public static void main(String[] args) {
        Size size = Size.LARGE;
        String toString = size.toString();  // toString is "LARGE"
        System.out.println(toString);
    }
}

In this example, the Sizeenum has four constant values: SMALL, MEDIUM, LARGE, and EXTRA_LARGE. The toString() method is called on the size variable and returns the String representation of the enum value.

You can use the toString() method to get the String representation of an enum value in Java. The toString() method is useful for displaying the enum value in a user-friendly way.
